Once again I totally agree. Thanks guys for your advices.
About mixing : For the moment I mainly use the 321 as attenuator / offset, and I plan to acquire a 3xmia for the same reasons because the voltage block suffers from a lack of attenuations (why malekko did not include this option ?? Why ??!!!). In addition to that, pamela is not bipolar, it will also be very useful to me to modulate its signals. I use my matrix mixer in combo of marbles (marbles 4 cv out, matrix 4 in, it looks like they were made to meet). Regarding tesseract and audio mixing, I think I overestimated my current needs a bit. On the other hand, I absolutely need to improve my stereo mixing capacity, so I think I will start with a single stereo module and drop the mono. The send / return will bring me a big plus to optimize the use of my effects / sidechains. For the rest, I don't have much left to buy to complete this project and it is indeed always a plus to have a little room to meet my future needs ... the maestro looks amazing !!!! I had heard about it without paying much attention to it. Just watched a video...this module looks totaly insane to perform on the fly! I want this !
Thanks again and sorry for my english wich is not my main language.
Cheers !
